To all whom it may coir/corn.-

Be it known that I, LEE WEST, a citizen of the United States, residingat Wellston, in the county of Jackson and State of Ohio, have in- 5vented new and useful Improvements in Apparatus for Applying Coatings ofMetal to Boiler-Tubes or other Articles, of which the following is aspecification.

My invention relates to apparatus for ap- IO plying a coatingof metal toboiler-tubes and other articles. It is my purpose to provide novel meansfor the accomplishment of this object consisting of a tank for thecleansing solution and flux, a furnace to heat the tubes to dryness andmelt the adhering films of fluxing material, a traveling crane and meansfor delivering the heated tubes thereto, a revolving furnace for themolten metal, in which the tubes are placed and from which they areremoved by the traveling crane, and means for delivering the coatedtubes from the crane to a tank containinga scouring solution, provisionbeing made for cooling the arm of the crane which enters the revolvingfurnace by internal water circulation.

It is my object to provide a novel construction of each of theconstituent parts named, whereby its functions'shall be discharged in anovel and efficient manner and the final resuit attained with the leastpossible expenditure of time and labor.

I also aim to accomplish other novel and useful results, all of whichwill be fully explained hereinafter and then particularly pointed outand defined in the claims at the end of this specification.

For the purpose of the following description reference is had to theaccompanyingdrawings, in which Figure 1 is a plan view of an apparatusconst-ructed and arranged in accordance with my said invention. Fig. 2is a front elevation. Fig. 3 is a vertical section on the line 3 3 inFig. 1. Fig. l is a similar section on the line 4 4 of Fig. 1. Fig. 5 isa sectional side elevation of the revolving furnace. Fig. 6 is avertical sectional view of the traveling and adjustable frames and aportion of the crane. Fig. 7 is a cross-sectional view of the travelingcarriage looking in the direction of the arrow, Fig. 6. Fig. 8 is across-sectionalview of the crane. Fig. 9 is a longitudinal section ofthe furnace on the line 9 9, Fig. 1. Fig.

10 is a sectional side elevation of the revolving furnace and crane,showing the crane within the furnace. Fig. 11 is a cross-sectional viewof the furnace, showing one position of the crane when delivering andwithdrawing the pipes or tubes.

In the following specification the several parts of the mechanism willbe referred to as nearly as possible in theorder in which theirindividual functions are performed in the practice of my invention.

The reference-numeral l in said drawings indicates a tank, which may beconstructed of cement or of boiler-plate, its length being such as toreadily admit therein the sections of tubing to be treated. In thistank, which I term .for convenience of reference the fiuXing-tank, isplaced a solution consisting of twenty-five parts of pulverized borax,five parts of muriatic acid, and seventy parts of Water. The tube ortubes to be treated are submerged in this solution.

Arranged adjacent to the fluXing-tank 1 is a furnace 2, provided at oneend with a grate 2 and a combustion-chamber at the rear of and above thelevel of the grate. The chamber 3 is provided with a top 4, formed witha series of perforations 5 and having a series of ridges 5 upon itsupper face on which the tubes rest. Thefurnace above the top 4 hasmounted thereon an arched metallic hood 6, lined with refractorymaterial 6, supported upon the inward ly-eXtendin g ridges 6 Pivotallyconnected to each side of the dome 6 is a plate 7, extending from end toend of the hood and which can be turned so as to open or close the spacebetween the horizon- 9o tal edge of the hood 6 and the upper face of thetop 4 of the chamber 3. The tank 1 is arranged alongside and parallelwith one of the sides of the hood 6, so that the tubes, after beingsubmerged in the solution in the 5 tank 1, can be rolled upon theperforated top 4: under the hood 6 and the plate 7 dropped. Heat isproduced by burning coal, oil, or gas in the fire-box, and the tubes aresubjected to a heat of about 1,800, which drives off I00 15, bracedapart by means of the cross-stays vided with aconcentricopening 19 45the water and melts the flux, forming a film or glaze :over the tubesinside andout.

"Upon the opposite side of the furnace, adjacent to. the tank 1, are aseries of horizontal bars 8, connected at their inner ends to a verticalsupport 8, pivotally connected to the keepers 8, secured to the side ofthe furnace. The outer ends of the bars 8 are suitably secured or formedintegral with the outer ends of the inclined brace or supporting bars 9,secured at their inner ends to the vertical support 8. These bars 9 alsoform stops to prevent-a downward movement of the vertical supports 8.The lower ends of each of the supports 8 are'bent atan angle, as attiand then vertically, forming a spur 12, upon which are mounted the eyesor loops 10 of the bar 9*, provided with the handle 12?. The bar 9 isadapted to swing, the bars 8 and 9 and {vertical supports 8 parallelwith and against the side of the furnace to which they are pivoted ortobe turned outward at right angles to the same. The bars 8 9 and verticalsupport form brackets, and the bar 8 is on a line with the perforatedwall 4, on which the tubes rest while heating, so that the lat: ter canbe readily rolled upon the former.

Parallel with and near the furnace is a framework .consisting ofvertical ends 13, supporting two elevated double rails 14 and tangularframe 18, constructed of theends- 18% connected together at their tops,bottoms, and sides by the horizontaland longitudinal braces 18 18,respectively.

Arranged withinpeach end 18 of the frame,

18 is a vertically-adjustable frame 19, pro- The lower part oft-heopening19, near the outer edge thereof, is formed with a lug or shoulder19*, the function of WhlClLWlll, behereinafter.

described. J ournaled in suitable brackets 19, secured to one side ofthe endslS of the frame 18, is a shaft 20, rotated by thehand wheel 20.Mounted upon the shaft 20 is a pair of spur-gears 21, each of which isadapted to engage a vertical rack-bar 22, secured to theinner face ofeach of the frames 19 and projecting over the ends 18 of the frame 18.By rotatingthe shaft 20 by means of the handwheel 20 the spur-gears,meshing with they rack-bars 22 will vertically adjust the frame.

23 by its engagement with the ratchet 20 is adapted to retain theframel9 in the desired position.

Arranged, in the opening 19 ofv each of the frames19 is a swivel-supportfor thecrane, and which consists of a pair of rings 24, con- Dependingfrom the platform 16 isnected together by means of the supportingrods25. The rings 24 are mounted in the openings 19 and retained therein bymeans of the lugs or shoulders 19". The swivel-support is adapted torevolve within the openings 19 Extending through the swivel-support isthe craneconsisting of'a pair of arms 26 27, formed of a hollow tube andbent in such amanner as to arrange the arms parallel with each otherandwhich are suitably connected to two of the rods 25. The arms 26 27are'constructed of tubing to reduce their weight and bentin the mannershown to permit of the circulation of water therethrough to keep theirtemperature at the proper point and are therefore connected to suitablewater su pply and discharge. pipes 26 27f, respectively. Atthefront ofthe-crane,adjacent to the coupling. connection 26* of the water supply.and discharge pipes, is asu-pport 27*, arranged between and. suitablysecured -to the arms 26 27 and to the swivel-'supporttand is providedwith a handle 27 for turning the. same, arms 26 27, and swivel-support.

Depending from the arms-26 2.7 are aseries of hollow rigid hangers-28,havingat their lower ends anchor-shaped hooks29, which lie in; positiontoreceive. the tube lyingon the,

eccentric 35, mounted on a shaft .35, having bearing in a floor-bracket36. The shaft is revolved by a pulley 37, driven by'anysuitablepower.The furnace 30 is heated bygas, oil, or pulverizedcoal supplied througha pipe 37, theproductsof combustion passing offthrough a stack .38. Theopen end ofthe furnace 30 is provided with a gate. 39, which slides uponvertical guides 40 andis raised and lowered-by a chain. 41, passing overgrooved pulleys 42 on the end frames 13, the weight of the gate beingcounterbalanced by a weight 43. Thefuel-feed pipe 37 passes through. aslot 44 in this gate. The inner face-of the furnace 30 is provided withgrooves or channels 45 fortheanchor-hooks 29.

On the other side of the. elevated railway from the furnace-2isastrippingor cleaning tank .46, the vertical walls of which, adjacent tothe.crane,' are provided with a series of tube-v supporting'bars .47similar to the-bars 8 and supported to form brackets and operated in alike manner and are substantially opposite the bars 8 and in similarrelation to the crane. They are extended or turned in against the tank46 by a bar 48 and are about on a level with the top of the tank 46, sothat the tubes deposited on them bythe crane can be easily rolled intothe tank 45. The latter contains a solution consisting of zinc, fiveparts; salam moniac, ten parts; muriatic acid, ten parts, and water,seventy-five parts.

The operation of the apparatus is as follows: Assume that a tube hasbeen placed in the fluXing-tank 1 and submerged in the solution therein,after which it is removed and entered into the furnace 2 by elevatingthe plate 7, the tube resting upon the perforated top 4: and beingsubjected to a heat of about 1,800", which drives off the Water andmelts the flux, forming a film or glass upon the inner face andperiphery of the tube. The tube is then removed from the furnace inanydesirable manner through the opposite plate 7 and placed upon the seriesof horizontal bars 8, the crane being lowered by means of the hand-wheel20', shaft 20, and spur-gears 21, operating upon the racks 22 of theframe 19. When the crane is lowered, the anchor-shaped hooks are carriedtherewith, so that the tube can be rolled from the bars 8 and be seatedupon one arm at one side of the hooks. The crane is then elevated, andthe bars 8 are then swung away from the tube by means of the bar 9 andits handle 12. The door 39 of the furnace is elevated and i the crane,with the tube, is pushed forward by sired time the crane is lowered insuch a manner that the opposite arm of the hooks will enter the grooves45 beneath the tube. The crane is then elevated, causing the hooks toengage the tube and be withdrawn from the furnace,carryingtheformertherewith. The bars 47 are swung outwardly, the tuberolled thereon and then submerged in the cleaning or stripping tank 46.When one tube has been placed in the furnace, it is usually preferableto withdraw the crane to receive another tube from the furnace 20! bars8 and which is pushed forward into the furnace 30, and when lowered anddropped from one arm of the anchor-hooks the opposite arm of the hookswhen the craneis elevated will engage the tube that was first placed inthe furnace.

The crane is now withdrawn and during the removal of the tube to thebars 47 a new tube is placed upon the arm of the book from the bars 8,making a continuous operation. Of

course it will be evident that the furnace 30 is constantly revolvingand that the door 39 is lowered, closing the inlet to the furnace 30when the crane is removed, and that the furnace 30 is heated by the pipe37.

This mechanism is especially adapted for plating boiler-tubes,water-pipes, and other metallic articles which are exposed to watercontaining lime, acids, and other substances which are likely to causedeterioration of the tubes or pipes, which can be rapidly and perfectlyplated with small expenditure of time and labor.
